SPECIFICATION forming part of Letters Patent No. 672,927, dated April 30, 1901.

Application filed December 31, 1900. Serial No. 41,725- (No model.)

To aZZ whom it may concern/.-

Be it known that I, ELMER E. WELSH, a citizen of the Unitedbtates of America, residing at Lawrence, in the county of Douglas and State of Kansas, have invented certain new and useful Improvements in Spike-Extraotors; and I do hereby declare that the following is a full, clear, and exact description of theinvention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forminga part of this specification.

The objects of my invention are, first, to obtain a bite upon the spike in degrees without crushing strain; second, to obtain successive applications of the bite expeditiously, and, third, to provide an easy transmission of the leverage required to operate the jaws.

The invention consists in the novel construction and combination of parts, such as will be first fully described, and then specifically pointed out in the claims.

In the drawings, Figure 1 is a view in perspective of the novel spike-extractor. Fig. 2 is a rear enlarged view in detail of the spikgrasping jaws, also showing the jaw-operating lever and the bell-crank lever on the lower portion of the bar. Figs. 3 are views, in perspective, of the stationary and movable parts of the spike-grasping jaws disassociated. Fig. 4 is a detail view of portions of the separate operating and jaw-adjusting levers, showing the pivotalshoulder-and-socket connection of the jaw-operating lever. Fig. 5 is a detail view in perspective of the sleeve on the adj Listing-lever.

Similar letters of reference indicate corresponding parts in all the figures of the drawin s. Tteferring to the drawings, A represents the main operating lever of the spike-extractor,

which consists ofa flat bar of'considerable degree, decreasing the width ofthe bar at its upper end.

At the lower end of the main .bar or lever A are the spike-grasping jaws BB. The jaw B, which is stationary, consists of a body portio'n'b,the front 17 and rear portion b of which .of oscillation.

are in the plane of the front and rear edges 0, a, of the lever or bar A.' In width said body portion extends a short distance beyond the plane of the sides of said lever. The upper ends of the sides b b of the body portion 19 are curved downwardly, and extend upwardly in the plane of the sides of the lever or bar A, and the forward portions of said upper ends are halved or cut away in a vertical direction. The lower end ofthe lever A is also halved at a and said halved parts are secured together by screw-bolts 17 thus enabling the body portion 1) to be readily detached from the lever A.

At the lower end of the body portion 12 is formed the spike-grasping part b pf-the jaw, which is about one-half the thickness of the body portion 1) of the jaw, the inner side of which is nearly fiat. The forward end of the part b and the rear end If extend beyond the plane of the front b and rear b of the body portion 1), and the lower rocking or under side b of the part b is formed in a single outwardly-curved line. On the inner side b of the forward part b of the jaw is anoutwardlycurved depression extending from the upper edge of said part b which forms one of the spike-biting surfaces of the jaw.

In the rear side of the body portion 19, directly above the part b of the jaw, is a circular depression or socket b", which extends about two-thirds the'distance toward the forward side b of the body portion b of the jaw, leaving the side of the socket exposed, and the shoulder b which extends downwardly from the side b of the body I) of the jaw and partially incloses the socket. The lower part b of the movable jaw B is the same as the part b of jaw B secured in position, and upon the upper end of the said part'b is a circular pivot or hearing I), extending about twothirds the length of the jaw B and within the socket b in the body I) of'the jaw B and fitting therein so as to move easily in the plane The outer side b of jaw B extends upwardly a short distance at the point of connection of the hearing I) and comes into contact with'the shoulder b when the jaws B B are opened to their widest ex-' tent. Through the body portion 1) of the jaw B and the side extends an openingb which extends concentrically to the socket b through the bearing 1), and through said opening extends a screw-bolt b", which has a head b at one end, and at the other end, upon said screw-threaded end, is a nut b the head Z7 being countersunk, as shown in the drawings.

With the rear end of the pivot or bearing Z) is connected rigidly the lower end 0 of the jaw-operating lever C, which extends upwardly in a curved line a short distance, and its upper end 0 extended a slight distance beyond the plane of the side of the lever corresponding to that of the side I) of the body portion of the jaw 19 having the shoulder b and in the upper end 0' of said lever is a longitudinal slot 0 D represents a bell-crank lever, which is arranged on lever or bar A, directly above the upper end of lever C, and is provided with a circular hearing or pivot d, which enters a socket d in the rear edge a of the lever or bar A. In the upper arm of the lever D is an opening (1. d is a pivot on the lower arm which enters the slot 0 in the upper end of lever C.

E is the power-transmitting and jaw-adjusting lever, which consists of a straight bar, the lower end of which lever is pivotally connected with the side of the bar A at a point about equidistant from the jaws B B and the,

upper end of lever E.

Upon the lower end of lever A is an arm e, short in length and extending at right angles thereto, and upon the inner side of the lower end of the lever is a laterally-extended shoulder or bearing 6', circular inform, which extends within a socket (2 which extends a short distance within the side of the bar or lever A, as seen in detail in Fig. 4. In the outer end of the arm 6 is an opening 6 in which is inserted the upper bent portion 6 of a rod 6 the lower bent end of which rod enters the opening (1 in the upper arm of the bell-crank lever D.

Upon the same side of lever A with that of thelever E and a short distance upwardly from the pivotal point of connection of said lever with said lever A is a segment-plate E, which is arranged in position at right angles to bar A and close to the inner side of lever E. Said segment-plate is connected with the side of the bar A by means of a short downwardly-extended barf, thelower end of which inclines inwardly and is secured by the screw f. At each end of the segment-plate are outwardly-extended portions or stops f which limit the to-and-fro movements of the lever E. In the upper curved edge of the segmentplate F are the notches f extending in series from one end of the segment-plate to the other. Extending loosely around the lever E, above the segment F, is a sleeve g, upon the inner side of which and extending from its lower edge toward bar A is a lateral extension g, a portion 9 of which also is bent downwardly at. right angles in the plane of the inner side of the segment-plate F. Upon the under side of the lateral extension 9' is a tooth 9 which of each jaw.

said pin extending through the perforation g in lip g and a short distance above said lip. Extending around the pin g between the lips g g, is a coiled spring g Upon the for- .ward edge of the lever E, near its upper end,

is a hand-lever G, at the lower end of which are the rear plates g and the short forwardlyextended arm g, which extend at right angles to the lever G, the plates g being pivotally connected with the lever E by the pivot 9 In the outer end of the arm 9 is a perforation, in which is extended the upper end of a short rod g", the lower end of which rod is bent at right angles and extended through a perforation in the upper end of the pin g In operation the bar or lever A is held in nearly anupright position with one hand, while the otherhand grasps the lever E, the same hand extending to and grasping the hand-lever G, in which grasp the lever G at its upper end is thrown against the forward edge of the lever E, drawing up the sleeve g a short distance and releasing the tooth g from the notehesf in the segment F. The lever E being moved forwardly against the forward stop f operates the bell-crank lever D, drawing upon the upper arm of the lever, and consequently moving outwardly the upper end of the lever cand opening the pin B its full extent, the shoulders b Z) in the respective fixed, and movable jaws coming intocontact. Thejaws B B are then moved forward to admit the head or upper part of the spike to be drawn and whichis seized between the parts b b on the forward part b v The grasp being retained'on lever G the lever E is moved rearwardly in degrees until the bite of" the jaws is snflicient to draw the spike, when the main lever'A is moved reawardly upon the curved bearing of the under side of the jaws, clutching the forward biting part of the jaws, and the spike is easily extracted. With the controlof'the lever E upon the jaws B B repeated grasps of the jaws may be obtained with rapidity, thus increasing the leverage to meetthe resistance :of the spike.

It will be observed that the grasp of the curs, and spikes or nails without heads and the parts of which are closein position to the tie are easily grasped and drawn from the tie. The construction of the novel spike-extractor-affords convenient operation between closely-related track-rails and a longer reach obtained in the forward and backward movement of the lever A than in ordinary spikeenter extractors and with a long or short purchase to grasp the spike and sufiicient to do the work. The amount of leverage required is also more readily applied to. the jaws than in other forms of spike-extractors, thus afiording an efficient and powerful implement.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is
